New and overwhelmed!!

Hi everyone! I'm new here and am overwhelmed by all the awesome information. I'm also confused as to how this all works.
We are planning a first time trip with our girls ages 6 and 15 and I'm wanting to make autograph books for them. I found a link with pages that you can print but I'm having a hard time figuring it all out. Can anyone direct me to some tutorials or help me out? Thanks so much. I'm soooo excited to learn and plan the trip of a lifetime for our family.
